High Temps 5800x3d with reduced voltage
Hello everyone, I’m facing some confusion. My Ryzen 5800x3d was struggling with high temperatures during Cinebench, hitting around 90°C. I have a Deepcool L240T cooler. In the top test it cooled down to 80°C with a -0.10 overvoltage setting, while in the lower score it reached 74°C with -0.143. I lost about 1000 points in Cinebench. What’s considered normal for that setup? Won’t this affect my gaming performance—like FPS or frame rates? I’m not very technical, so please clarify if I misunderstood anything. Thanks!
The 5800X3D often heats up during all-core tasks since the CPU's heat must pass through the V-Cache before reaching the cooler. It's normal for it to reach temperatures around 80°C. During light gaming sessions, it won't get that hot. Consider reverting to a -0.10v setting if you're okay with that—clearly it dislikes aggressive undervolting when your Cinebench score drops by nearly 10%.
In Call Of Duty (Warzone 2.0) I hit 75Cº in the flight simulator and reached 80Cº. Both games ran at Undervolt -0.10; I'm unsure if it's an advantage, but the clock increased by 0.50mhz with Undervolt -0.15 (offset) and 73º (cinebench r23).
They're built to handle temperatures up to 90°C before performance drops. Seeing 80-85°C during a synthetic test shows all cores are working well. This isn't great if the result was lower, unless the heat makes it more pleasant.
Don't worry about adjusting vcore offsets at all. Setting -30 in the curve optimizer should suffice. The process varies with your room temperature as well. You can observe that I reached 70°C while the furnace was active. I allowed it to run for 10 minutes and maintained 15K. Edit: I only have a single stock fan on my CPU, and none of them reach full speed.
